Retrieval of Nighttime Aerosol Optical Thickness from Star Photometry

open access: yesAtmosphere, 2015
In this study star photometry was applied to retrieve aerosol optical thickness (AOT) at night. The star photometry system consisted of small refractor, optical filters, CCD camera, and driving mount and was located in Suwon. The calibration constants were retrieved from the astronomical Langley method but standard deviations of these were more than 10%

Aerosol optical properties and a new methodology to retrieve aerosol optical thickness from satellite over São Paulo

open access: yes, 2005
A poluição atmosférica é hoje uma questão que afeta as megacidades por todo o mundo. As partículas de aerossol participam do balanço radiativo, da formação de nuvens, da química atmosférica, e são prejudiciais à saúde da população exposta. A extensão e o

Measurement and modeling of diffuse ultraviolet radiation: A review

open access: yesPhotochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Spectral characterization of three wearable electronic ultraviolet radiation dosimeters

open access: yesPhotochemistry and Photobiology, EarlyView.
Excessive exposure to ultraviolet radiation poses significant public health risks, including DNA damage and skin‐related pathologies. Wearable electronic UV dosimeters enable accurate studies and quantification of solar UV‐radiation exposure on an individual level. Due to variations in the spectral distribution of solar radiation, the spectral mismatch

Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

open access: yesPhotochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.
